"UNITED STAT] w HORATIO LEoNAnD Nn HENRY RYDER, or nnw .BnDFonD I To all'whom it may concern? Be 1t known that we, HORATIO LEONARD Y I iniimnnrus For; MOLDING cAnianns.

Specification of Letters I Patent and HENRYRYDER, ofNew Bedford,in the county of Bristol and State of Massachu setts, have invented an Improved Apparatus for Molding Paraffin or other Candles;

and we do hereby declare that the sameas fully described and represented in the fel lowing specification and the l accompanying drawings, of which- 1 a Figure 1, denotes a side elevation of the said apparatus; Fig. 2, a top view. Fig. 3, is a vertical and longitudinal section, taken through one series of the molds. Fig. 4,

denotes a top view'as it appears with the receiver or trough removed. Fig. 5,.is an underside view of said apparatus, and Fig. 6, is an underside view of the receiver or vessel for receiving the melted parafiin. i

In the manufacture of paraflin candles, it is found that their contraction in the molds during the process of cooling or hardening, is very little, and that they adhere so firmly to the molds, as to render their removal therefrom, very diflicult, particularly if the molds are constructedulike those usually em ployed in making sperm, tallow and stearin candles; and besides the paraffin being so rlch in carbon, renders 1t necessary to make their wicks much smaller in diameter, than those of sperm, wax, tallow or stearin, and consequently it is entirely impracticable, if

not impossible, to extract the candles from their molds by draft on their wicks.

To overcome this difficulty has been one great object of our invention; the nature of which consists, first, in a peculiar construction and application of aremovable receiver or trough to the top surface of the mold or series of molds, whereby when the molds may have been filled with the araflin or material to be molded, the surp us left in the said receiver, when cooled shall form a plate or serve as shoulders to the candles, whereby they can be easily extracted from their molds, by simply raising upward the receiver. I

It also consists in a peculiar mode of packing or closing the orifices at the lowerparts or tips of the molds in order to prevent leakage therefrom, the same being as hereinafter set forth. l In the drawing, A, represents the frame of the machine or apparatus, which is provided with one or more series of molds, B, B, B, B, &c., arranged in the frame as shown No. 26,440, da'ed beceinber 11 through holes, formed through the flanges,*;

The surfaces the molds come up flushiwithiaz horizontal imea, I tallic plate, C, and are.firmlyqsecuredtthere 5 a 3. to in the usual manner;IThe body ofyeach f mold is of a cylindricalior slightlyitaperingf Q- shape, and'has a conical l tip; offitheusua jlj form applied to. its lower. end. ,1 "Forthe fpur pose of renderingfthei lower end of the tipk, j, or the wick orifice tight, or soasto prevent f leakage therefrom, weapplyl; tomtheulowerfl 11 longitudinal bar, D,wone;or more series of 1. Y springs, or elastic bars,a,lfla,ia, &o.g(corresponding in number withthernumberiofthe molds) each of which; is"? provided, on fitslfltop f surface',with a strip? of india rubber, 0, or 1- other suitable elasticmaterial, as lshown in {it I the drawings. The inner end of eachof such springs being so, connected to the said bar by meansof pivots orflscrews,jas to rep; der them capable of being slightly rotated, so as either to bringjtherubberin cont-act j y, with the tips, or remove ittherefrom ascir j cumstances may require. 1} a For thepurpose of enablingustoremove1 801 I the candlesfrom thejemoldsfwhen formed) we make the trough orfreceiverE, separate. from the molds, and soapplyfitthereto as to enable it tobe easily removed therefrom. 1 The said receiver has a; rectangular,or any 8 5 other proper shape, asljshown thedraw-f ings, and is secured to the frameA,;by means f ji of vertical standards, G, fG, f extending up from the sides of theframe and passing x cl, (l, of the receiver,the same being as shown in Fig. 2. Moreover, tapering keys,1c,; c, passing through the vertical standards, serve to keep the receiverin its proper position. Through the bottom of said receiver or trough, cylindrical or other proper shaped holes, corresponding in number with; Qthej number of the molds, are made, each having a diameter a little greater thanthe top of a the mold overwhich it is tobe placed-and .1010] moreover,in order to jinsureja perfect or p 1 water tight connection between the receiver,

E, and the molds, B, B, &c., weform on the, H underside of said receiver, and around each j hole made through it, a hollow cylindrical extension L, (as shown in Fig. 6,) which j} rests on or is packedlby asheet of yulcali ized rubber or other suitable elastic mate a rial, which is firmly confinedtothe plate, G, l 1 f by means of a metallic] plate,H, formedas lq shown in Fig. 4, andmoreover, the Isaidy sheet of rubber has cyli drical holes, cut\ i through it, correspondin in diameter to that of the base of each mold, the center of the mold, the center of the packing, and the center of the extension being supposed to be in the same line. Furthermore on the top of the said receiver, vertical projections, b, b, b, b, are cast or formed as shown in Fig. 1, the same having holes or slots formed horizontally through them, for the reception of rods or bars I, K, around which the Wicks of the candles are to be passed.

By the above arrangement of parts, We are enabled to make a perfectly tight connection between the receiver and the molds.

In operating with the above apparatus; after the molds have been filled with paraffin, and the candles become sufficiently cooled, we first remove the keys from the vertical standards, so as to allow the trough to be raised upward. Next by taking hold of the projections or flanges, d, d, we raise the said receiver upward, and the candles from the molds. After they are drawn out we saw them off just below the cylindrical projections, L, L, &c., on the underside of Q r V 7 20,440

the receiver. The receiver is next reheated, and'the tops of the candlesor surplus material in the receiver melted, the rods are then removed, and the portions of the wick taken from their bars or rods.

Having described our invention, what we claim, is as follows 1. We claim making the receiver or trough, E, separate from the body of the mold, or series of molds,- and so constructed and arranged as to operate therewith, substantially in manner, and for the purpose set forth. I

2. We alsoclaim the herein described im proved mode .of packing the lower orifice of the mold, viz. by means of a spring, a, furnished with rubber or other proper elastic material, the same being arranged and made to operate with respect to the said orifice, as set forth.
